No Electronic circuitry and relay circuit uses 2 different rails. (They are 2 indipendent 240V to 5V smps )
I Will be using ATMEGA2560AU in my circuit with lots of decoupling capacitors.
Yea i want to suppress the noise locally, so what are the ways to do that..
Hai,
I am building a circuit based on atmel, the circuit will have to trigger relays. The relays used are 5v Relays ( The small cube shaped ones ). In the initial prototype i Noticed that arduino resets when relay unlatches. I want the circuit to be rock solid. So Have done following things...
Hai,,
iam having network registration issues with SIM800L. It was working fine with the same sim card for last many days but suddenly it stopped working. Now It doesnt connect to network, AT+COPS= returns all the available networks
I enabled AT+CMEE=1 and did AT+CPIN.
and i got reply as +CME...
Iam sorry.. i was away from forum for a few weeks.. i met with a serious car accident and was on bed for sometime.. :) Just recovering. So now iam back into this. With new circuit using moc3023.
Moc seems to work.. I can drive the moc from pic and blink led. Let me write a program to do...
Directly in the sense.. I just removed pic
Now its vcc 150ohm moc
I even tried direct 5v..
I tried with different moc
Ioad is a 40 watt incandescrnt bulb
Now iam trying to figure out if my MOC is working. I separated pic for now and i am directly powering MOC. But that doesnt activate TRIAC too.
How can i basically test if MOC is faulty
Hai, iam but familier with PIC programming, But this time one issue is giving me a big headache.
I am using PIC12F1840, i am not able to get output on RA4.
It simply gives zero volt, When i attach a 10k pullup It constantly gives me 5v.
i have set TRISPIN, I have disabled adcon etc..
The...
Voltage across pin 1 and 2 is 1.33
Voltage across pin2 and ground is zero,
i tried connecting moc directly to 5v, it still doesnt activate triac. Is my entire lot of moc faulty ? :)
By the way whats the minimum voltage that Moc should get
- - - Updated - - -
Attaching my circuit,
Triac is bt...
I am trying to make a digital dimmer circuit,But i was not successful so i was finding fault part by part Lets leave the ZCD and microcontroller thing apart for now.
I am using M0C3020 and bt138. I tried powering up Moc directly but that doesnt turn on triac.
So my connection is as follows
I...
